Disclaimer: It's been ages since I've compiled a darn thing... Feel free to tell me to RTFM... just point me in the right direction first :)

I'm having a hell of a time getting hiptext compiled... Looking to do this from OS X and I've been using MacPorts, since it seemed like the easiest way to grab most of the dependencies you'd listed (grabbed ffmpeg, wget for your install-g*.sh scripts, and ragel). I believe I'm using gcc4.8 — at least the MacPorts version.

At this point when I make I'm getting an output of:

At this point I haven't the foggiest as to what I should try next. :/ Any suggestions, are hugely appreciated.

This PR is a quick implementation of SIXEL graphics(Issue #16).

It introduces the following new options.

-sixel2 : emit monochrome sixel
-sixel16 : emit 16-color sixel
-sixel256 : emit 256-color sixel

Note that we can get more beautiful picture using palette re-definition sequence If this software can do dynamic-palette quantization method(such as median-cut), but I didn't know how to do it.

DEMO

• mlterm (it works with X11 / frame buffer / win32 version, http://mlterm.sourceforge.net)
• xterm with "-ti vt340" option (color palette is limited up to 16)
• RLogin (Japanese high spec terminal emulator. it also implements ReGIS. see http://nanno.dip.jp/softlib/man/rlogin/#REGWIND)
• tanasinn (A firefox extension, see http://zuse.jp/tanasinn/)

I tested this patch on above 4 terminals.

I was wondering whether xterm's support for sixel graphics might offer higher-quality output. (Dunno if any other terminal emulators support sixels. I'd be surprised.)

If i run hiptext from the directory I compiled it from it works fine. After running make install I get an error on the same images that it previously displayed without errors.

configure: error: Package requirements (libgflags) were not met:

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBGFLAGS_CFLAGS
and LIBGFLAGS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

When I use make -j4 to compile the program , a source code called 'pixel_parser.cc' has missed. I wonder where could I find this file, or wasI just did something wrong ?

To build this on ubuntu 1604 the configure will fail to find libgflags.pc which was missing from ubuntu. I added it manually to /usr/lib/x86_64-linux-gnu/pkgconfig/libgflags.pc with content like:

prefix=/usr
exec_prefix=${prefix}
libdir=${prefix}/lib/x86_64-linux-gnu
includedir=${prefix}/include

Name: gflags
Version: 2.0
Description: A commandline flags library that allows for distributed flags
URL: http://code.google.com/p/gflags
Requires:
Libs: -L${libdir} -lgflags
Libs.private: -pthread -lpthread
Cflags: -I${includedir}`

On ubuntu 16.04 x86 I got : src/font.cc:6:22: fatal error: ft2build.h: No such file or directory

I manually added -I /usr/include/freetype2 to get it compiled, something configure script did not get the include path right.

… apparently the Apple/BSD signal.h interface is exactly the same as what’s on Linux, except for this. The codebase as it stands, on master at HEAD, errors out during make like so:

asio-otus:hiptext[master]$ make
c++ -g -O3 -std=c++11 -Wall -Wextra -fno-exceptions -fno-rtti -MD  -march=native -c -o hiptext.o hiptext.cc
c++ -g -O3 -std=c++11 -Wall -Wextra -fno-exceptions -fno-rtti -MD  -march=native -c -o artiste.o artiste.cc
artiste.cc:165:3: error: unknown type name 'sighandler_t'
  sighandler_t old_handler = signal(SIGINT, OnCtrlC);
  ^
1 error generated.
make: *** [artiste.o] Error 1

… but if I include the one alias per the PR, hiptext builds OK (with both Apple Clang 6.2 something and also LLVM Clang, somewhat recent HEAD from the 3.7 branch) and but then everything runs completely as advertised in every way thereafter:

Yes!

The functions "CleanUp" and "exit" do not belong to the list of async-signal-safe functions. Should these calls be replaced by a safe alternative in your function "OnCtrlC"?

Thank you for the resources I would like to ask how are they based on our de based on the English or are they converting the letters into English characters or ask characters I have tried to run it and I didn't understand which comments that I should look on it seems that you have committed something four months ago is it related with four years ago as well thank you so much

Hi there, there are some changes in ffmpeg and so the interface call signatures have been changed. Update this please, so we can all enjoy the ascii goodness

Even if you specify -width and -height, it tries calling ioctl TIOCGWINSZ, fails and crashes. ┐(´д｀)┌

Ran into this trying to use hiptext as an image preview in ranger.

Hi, pixel_parse.cc is not in the repo. And it's very weird :

$ wc pixel_parse.cc -l 17970

$ grep goto pixel_parse.cc | wc -l 7592

7592 GOTO !!! It's just insane ^^.

error occur in ffmpeg 4.0

src/movie.cc:70:38: error: use of undeclared identifier 'PIX_FMT_RGB24'; did you mean 'AV_PIX_FMT_RGB24'
src/movie.cc:94:5: warning: 'av_free_packet' is deprecated
src/movie.cc:65:22: error: use of undeclared identifier 'avcodec_alloc_frame'

send pull requests https://github.com/jart/hiptext/pull/52 but Travis CI refused because of using the earlier ffmpeg
